Marketingcharts.com reports on a survey by Burst Media which it says shows just how little tolerance users have to ad-cluttered sites.

• More than half say they have a low tolerance for more than two ads per page
• 27% say they will only tolerate one ad per page
• Just over 25% say they will only tolerate two ads per page

And the more ads, the less well they work, according to the piece.
